Title: Improved radio receiving equipment for omnidirectional phase beacon navigation systems
IPC: G01S1/02
Filed: 1953-12-04
Abstract: 736,281. Radio navigation. RADIO CORPORATION OF AMERICA. Dec. 4, 1953 [Jan. 2, 1953], No. 33806/53. Class 40 (7). In order to reduce random noise interference and so enable satisfactory determinations at longer ranges than previously the receiver for a phase comparison type omnidirectional beacon is provided with narrow band filters in each of the two channels feeding the phase comparison device. As a small drift in the tuning of these filters may introduce relative phase shifts in the signals passing through them checking and correcting arrangements are incorporated. In one embodiment, in which the signals which are to be phase compared are assumed to be of a frequency of 30 cycles per second the radio frequency signals from the beacon are received by antenna 1 and fed to receiver 3 which provides two outputs at 5 and 7. The output at 5 is the 30 c/s. reference phase signal and that at 7 the 30 c/s. variable phase signal. The output at 7 is fed to filter 11 which may have a pass band of 27-33 cycles per second and thence to the phase comparison device 13. The output at 5 may be coupled by switch 9 through adjustable phase shifter 15 and filter 17 (which may be identical with filter 11) to the other input of phase comparison device 13. To check if there is any relative phase shift introduced by the two channels switch 9 is moved to the position shown so that the same signal passes through both channels; any deviation from zero phase difference indication is then corrected by adjustment of phase shifter 15 and the switch 9 return to its normal position on contact 5. Either signal received may be fed through both channels to effect the phase shift check.

Title: Electric inductive apparatus
IPC: H01F27/28
Filed: 1963-08-27
Abstract: 986,323. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. Aug. 27, 1963 [Sept. 10, 1962], No. 33822/63. Heading H1T. An inductive winding is divided into two or three zones each zone consisting of a number of coils having their turns interleaved to reduce surge voltage stresses, the inter-turn insulation being thinner in one zone than in the other zone or zones and, to compensate for the capacitative effect of this, the degree of interleaving being less in that zone than in the other zone or zones. The coils having thinner inter-turn insulation have, in consequence, more turns. For a winding not having a neutral or earth connection at one end there are two smaller end zones I and III (Fig. 1) in which the inter-turn insulation H is thicker than the insulation H<SP>1</SP> in zone II. In zones I and III the turns of one coil are interleaved with those of an adjacent coil so that the number of turns electrically in series between physically adjacent turns is greater than in zone II where the turns of each coil are interleaved only with one another. Where one end of the winding is connected to neutral or earth only two zones I and II are necessary. Various ways of interleaving the coil turns are described and shown including arrangements having twoor three parallel paths through the winding.

Abstract: 1,263,603. Activating sorbents. INSTITUTT FOR ATOMENERGI. 4 July, 1969 [6 July, 1968], No. 33861/69. Headings B1L and B1X. Sorbent 5 to be used in the sorption or separation of gas mixtures, e.g. by gas chromatography, is activated by heating to >300‹C in silicon tube 1 surrounded by heater 2, the temperature being controlled by thermocouple 4. After a suitable period of time, wire 7 is wound up on spool 8 causing steel wool plug 6 to be displaced, whereby sorbent 5 falls into tube 9 immersed in liquid nitrogen 11 and the heated sorbent is thereby rapidly quenched to <-75‹C. The heating and quenching may be carried out either in a stream of inert gas or alternatively under vacuum. Suitable sorbents for such activation are alumina, bauxite, molecular sieves Types 4A and 5A, and a granulate mixture of magnesia and silica. Sorbents so treated are particularly suitable for selectively retaining radioactive isotopes of krypton and xenon formed during nuclear fission when irradiated nuclear fuel is being reprocessed as well as argon oxygen and nitrogen.

Title: Production of rutile from ilmenite and related ores
IPC: C22B34/12
Filed: 1957-10-30
Abstract: Rutile is prepared from ilmenite by heating ilmenite to a temperature between 600 DEG C. and 1000 DEG C. in an oxygen free atmosphere containing free sulphur vapour, cooling, and then treating the product with water and free oxygen at a pressure between 20 psig and 100 psig at a temperature between 100 DEG C. and 200 DEG C., thereby producing granular skeletal rutile aggregates together with a hydrated iron oxide sludge and sulphur globules, from which the rutile aggregates are thereafter separated physically.  The oxygen free atmosphere may be maintained by the presence of carbon or carbon monoxide.  The free sulphur vapour may be derived from pyrite, boiling elemental sulphur, or hydrogen sulphide, carbon disulphide or other compound which at the temperature of the process decomposes to give free sulphur.  If the rutile product contains impurities not removed by the above, for example chromium or manganese, they must be removed by conventional ore-dressing methods.  The leached rutile product may be further freed of the remaining sulphur and iron oxide by washing, drying and then washing with a warm concentrated acid.
